Doomscrolling can steal hours of your time -- here's how to take it back

Doomscrolling can steal hours of precious sleep if you aren't mindful of the time.

(CNN)You're mindlessly scrolling on your phone after a long day at work, sifting through miles of negative posts.

In what seems like minutes, hours have gone by.
Doomscrolling has become a popular word over the past year to describe the habit of mindlessly scrolling through negative news. People lose their perception of time while scrolling on their phones, said Jeffrey Hall, professor of communication studies at the University of Kansas in Lawrence.
    Hall has spent over 10 years studying technology use in conjunction with relationships and is the director of the Relationships and Technology Lab at The University of Kansas. The lab focuses on how people incorporate digital technology into their everyday communication.

        CNN: How do people get sucked into doomscrolling?
        Jeffrey Hall: There are actually three parts to this that are worth paying attention to. One has to do with the way that social media companies design their product and the user experience. Another has to do with the user interface with that algorithm and the way it's designed. And third has to do with the way that we are attentive to negative information.
          Social media companies' express goal is to gather more information about our viewing habits to capture our attention for longer periods of time. This is so they can monetize that behavior with the purpose of selling it to advertisers.
          The algorithms are designed to maximize the amount of time people are paying attention to the app, and they evolve based on user engagement. What you click on, what your eyeballs spend more time on, what you reinforce in your scrolling, tells the algorithm what you want to see more of. It becomes a funnel where you see information you're not interacting with less and less.
          The third part has to do with your own attention processes. People tend to have what's called negativity bias when it comes to information. From an evolutionary perspective, it's related to the idea that we needed to be more alert to threats. If things are not particularly surprising, we can reside in a very low energy state, but as soon as we see something that's potentially threatening or worrisome, it piques our attention. The algorithms are picking up on what we engage in, and our attentive processes tend to focus on the more negative information.
          CNN: What are some ways people can prevent doomscrolling?
          Hall: A researcher a long time ago said something to me that I thought was really smart. She said, "I'm constantly training my algorithm." Wh
